There are two aspects:
1) undoing magic quotes (if it's being used).
This must be done for all GET and POST string inputs.
It is now done automatically by get_str() and post_str().
The places that refer to $_GET and $_POST directly
must do it themselves using undo_magic_quotes().
2) Escaping user-supplied strings before using them in DB queries.
This is done by process_user_text()
(which should be renamed db_escape_string()).
The new principle:
call process_user_text() in the function that does the DB query
(not at any higher level).
